摘要:
A system and method are described for the production of color selection swatch cards for point of purchase displays of custom blended paints, textiles or plastics using a digital inkjet printer and custom blended inkjet inks based on a set of base inks that can be blended using commercial match prediction software. The base inks are matched spectrally to the base paints, dyes or plastics.
摘要:
A system and method for producing a wide range of metallic appearances using halftones of a nano-particle metallic ink, such as, for example, nano-silver, are presented. In exemplary embodiments of the present invention, a nano-particle metallic ink, such as, for example, nano-silver, can be made to produce a range of appearances from, for example, bright silver to dull oxidized aluminum, by changing halftone level of the silver inks, changing the substrate surface properties and introducing small amounts of other colored inks, such as process or spot, in either an underprinting or overprinting of the metallic ink. In exemplary embodiments of the present invention, InkJet printing of a single metal-pigmented ink can be effected, and its metallic appearance can very quickly be adjusted to match a given package design.

A process is disclosed to measure or monitor ink concentration or ink thickness of an ink film as printed on a printing press, which consists of measuring light reflected from the ink film and the ink substrate.
摘要:
The present invention relates to a system and method for electronically communicating, coordinating and disseminating product designs, specifications and production-related data between a plurality of parties. More particularly, the invention relates to the coordination of parties that create color and graphic designs, including manufacturers, designers, suppliers and printers for new or existing color products.
摘要:
A system which enables electronic communication, coordination and dissemination of color-related designs, specifications and products. Color production and maintenance in a simultaneous fashion is provided between a plurality of disparate parties in substantially “real time.” The present integrated color-production is capable of importing electronic output from many diverse instruments, including color production-related hardware and software, and further uses the output to automatically deliver product data to and from a plurality of geographically disbursed parties. The present invention also provides an electronic library comprising colors and textures to be used for accurately matching a color sample and/or specification. The integrated, on-line color-related production system of the present invention enables parties to operate at peak efficiency, producing high sales and customer satisfaction.
摘要:
In the development of custom SPOT color inks, there will be only a single combination of pigments that will produce the correct color for both the solid tones and for one or more halftones intermediate between the full tone and the unprinted substrate. A novel system and method is presented for finding such a combination of colorants without requiring a complex suite of software algorithms. The method includes a search of a library of known colored inks printed onto a specified substrate and printed using specified printing conditions. Each record of such a library can contain, for example, the ink formula, the combination of colorants and resin, the spectral reflectance factor of the ink and substrate, color values (XYZ and CIELAB) of the solid ink color (100% tone) and 10% steps down to 0% (unprinted substrate). In such a database halftones can be specified in units of % (0% to 100%), but can also, for example, be given as 8-bit integers (0 to 255). In exemplary embodiments of the present invention, such a search locates the solid ink color that meets the color requirements and simultaneously meets the color requirements at one or more intermediate halftone steps. The claimed method can thus achieve a printing ink formula that produces a color match to a customer proof at both the solid color and at one or more halftones with ink coverages lying between the unprinted substrate (0% tone) and the fully printed substrate (100% tone).
摘要:
A method of estimating the trap of an overprint of at least two primary colors from the spectral density curve of the overprint by computing the amounts of the two primary colors that will produce a spectral density curve that matches the spectral density curve of the overprint, and then relating the amounts to one another. Also disclosed is a printing method that utilizes the trap estimation method. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader quickly to ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the appended issued claims. 37 CFR § 1.72(b).
